Inventor: ONO HIROYASU
IPC: H04M3/00
Filed: 1992-01-27
Abstract: PURPOSE:To unify the handling of a general terminal and a moving terminal so as to obtain a communication equipment which eliminates the need for a large amount of memory capacity by executing calling to a call control node which is attributed the last time in the case of judging the change frequency of an anttribution destination to be few. CONSTITUTION:A call control part 102 inside the plural call control nodes 1-1 to 1-3 refers to attribution destination change frequency data concerning the incoming terminal of an incoming terminal control memory 103. When there is no history of a call so that the valve of attribution destination change frequency data does not exit, or when the valve of attribution destination change frequency data is large than a threshold value, a call processing is executed to a terminal attribution destination control node 3. When the value of attribution destination change frequency data exists and the value is equal to below the threshold value, the nodes 1-1 to 1-3 which the terminals 2-1 and 2-2 are attributed to at the time of the preceding call are judged to be an incoming call destination. By this conbiguration, the general terminal and the moving terminal are uniformly handled and the communication equipment which eliminates the need for the large amount of memory capacity and processings is obtained.

CONSTITUTION:Combustion gas 8 being introduced into a gas way 7, water is let flow from a water-supply port connecting tube 5 into a heat-transfer tube 2. When the thermal value of heat exchange exceeds the thermal value at which the former reaches the saturation temperature corresponding to the operating pressure of water supply, steam is produced in supplied water 9 inside the heat transfer tube 2 and there appears a mixed state of water and steam. The supplied water 9, being given centrifugal force by the effect of the heat transfer tube 2 and a baffle 3 eccentric to piping header 1, flows along the inside of the header, except for steam, and then out from an outlet connecting tube 6 in the lower part of the header, and further is introduced in the water-side part of the body of boiler, while the steam in the supplied water gathers around the center of the header 1 and is introduced through a steam discharge tube into the steam part of the body of boiler. Based on the composition, a steam separator can be provided irrespective of the type of boiler and steam can be separated from supplied water.

Title: Manufacture of iii-v compound semiconductor epitaxial wafer
Inventor: NAGAI HISATAKA
IPC: C23C16/46
Filed: 1994-02-04
Abstract: PURPOSE:To eliminate the supply of the material, which contains P and has been conventionally supplied for the prevention of the desorption of P from a substrate, at the time of heating the InP substrate to the growing temperature of an InGaAs film, eliminate the cost of the material that contains P and the safety countermeasures taken for the material, reduce the cost and improve safety. CONSTITUTION:An InGaAs thin film 3 is epitaxially grown on an InP substrate 1 at a low growing temperature which does not permit the P of the InP substrate 1 to desorb, namely at the growing temperature of an InGaAs film 2 or below and the lowest growing temperature of the InGaAs film 2 or above. Then, while continuing the supply of AshH3 after the growth, the InP substrate 1 is heated to the growing temperature of the InGaAs film 2, and the Inlays film 2 is epitaxially grown. Thus, the InGaAs thin film 3 is permitted to operate as the buffer layer that prevents group V elements from desorbing from the InP substrate 1, and since the InP substrate 1 is placed under As excess pressure by supplying AsH3 while heating the InP substrate 1 to the growing temperature of the InGaAs film 2, the P is effectively prevented from desorbing.

Abstract: PURPOSE:To automate cutter replacement by providing a detaining part in a spindle, fitting a detent to be detained with detaining part coupled with a drive mechanism to make driving from outside in an adapter, and fixing adapter with cutter to the spindle. CONSTITUTION:A replacing unit B is actuated by a piston 15D to advance from (A) to (B) position, and grippers 15A grip the base 9 of an adapter 2 with the peripheral surface. A motor 19 rotates a gear 13, and a detent rotates in the direction of loosening to allow a fitting member to separate from the opening in a spindle 1, and then the unit B is sunk to the (C) position, and now the adapter 2 can be removed from the spindle 1. Then the unit B is retracted from (C) to (D) position, and the grippers 15A are opened by the piston 15D, and now the adapter 2 separates from the unit B. Accordingly a new adapter is gripped by the grippers 15A, and positioning is returned to (C), followed by rise to (B), and if the motor 19 is now reversed, the gear 13 will also rotate reversely to cause rotation of the detent in the direction of fastening, whereby the fitting member is automatically put in close contact with opening 1A and fixed thereto. Thus unmanned operation is made practicable.

Title: Work cutoff method
Inventor: MURATA TETSUO
IPC: H05K13/02
Filed: 1985-01-25
Abstract: PURPOSE:To get rid of any interference between works in time of their returning, by cutting off each work sideways in front of a tip end part of a conveying line chute and transferring it onto a transfer device. CONSTITUTION:Making full use of an opening 1b ranging from a tip end of a conveying chute to the tip end side, a work 41 at the tip end is cut off sideways (B) in the front in interlocking with a chuck head 3, and the work 4 is transferred to the chuck head 3. Therefore, when the chuck head 3 fails to operate by design or by mistake as well as when the work 41 is put back to the conveying line chute 1, there is distance of X between a return passage of an angular part 51 of the work 41 and a position of an angular part 52. Therefore, such trouble that these angular parts 51 and 52 hit themselves and interfere with each other is preventable from occurring.

Title: Trochoid type oil pump
Inventor: YOSHIMOTO AKIO
IPC: F04C2/10
Filed: 1989-01-20
Abstract: PURPOSE:To contrive the increase of a high speed flow amount or the like by setting a sealed position, having a seal round, with a delay for the maximum position of a between-teeth chamber, formed by an internal tooth of an outer rotor and an external tooth of an inner rotor, and providing a runway of shallow step difference from a partition start position of the sealed position to a between-teeth chamber maximum position side of a suction port. CONSTITUTION:For a maximum position P2 of a between-teeth chamber S, a sealed position P3 is set delaying about half tooth to a position of the between-teeth chamber S decreasing a little from the maximum. A seal round 10 is formed by providing a partition 10a in a round partition start position P4 and a partition 10b in a contact position P5 in a rotational direction delay side of the partition 10a. A runway 11 of shallow step difference is formed communicating in a staircase shape with a suction port 8 in partitions 10a and 8a. The runway 11 in the maximum position P2, by generating a positive pressure, eliminates a bubble generated in oil in a suction side in the time of high speed rotation, actively assisting a charge of oil by that amount of eliminating the bubble. Consequently, charging efficiency of oil is increased, accordingly a delivery flow amount is increased. It is preferable for the runway 11 to be set to a range of at least 5 to 25mm.

Filed: 1988-01-22
Abstract: PURPOSE:To equally offer shared resources to all processors by inhibiting the continuous accesses to the shared resources by avoiding the access request signal at least for one block period in a continuous access mode to the shared resources. CONSTITUTION:In case a processor 3 which is processing data with an access given to the shared resources wants to have a successive access to the shared resources, an arbitrating circuit 9 works to inhibit the access request signal for one clock period. In this case, another processor 4, for example, gives an access request to the shared resources. When said one clock period passes and to access request is received from other processors to the shared resources, the circuit 9 works to give the access right to the processor 3 again.
